php - 调用未定义的方法 App\Console\Kernel::load() - Laravel 5.4

Question

我将我的应用程序从 5.5 to 5.4 降级当我运行 php artisan serve 时出现此错误

Call to undefined method App\Console\Kernel::load() - Laravel 5.4

查看其他解决方案，我运行 composer dump-autoload解决此问题，但问题仍然存在。同样的错误。我真的不知道这是否是由我在下面发布的 composer.json 文件中的包引起的

我现在能做些什么来解决这个问题？

提前致谢

问题是您没有确保将代码更新为与 Laravel 5.4 兼容。

在 Kernel.php Laravel 5.5+ 附带的样板文件

$this->load(__DIR__.'/Commands');

此命令是在 5.5 中添加的，用于自动检测 app/Console/Commands 目录中的任何命令。

为了让此代码在 5.4 中工作，您需要删除该行并在 protected $commands = [ ] 下手动注册所有命令。数组在同一个文件中。
load的源代码在 https://github.com/laravel/framework/blob/5.5/src/Illuminate/Foundation/Console/Kernel.php#L196如果你想尝试适应它并把它放在你自己的 Kernel.php
